Add details of new property "label" for GPIO label name.

Why are there two properties for the same thing? Why not just allow
line-name to have multiple entries instead of introducing a new property?
We can use the lin-names also but per disucssion on the patch V1 of
gpio: of: Add support to have multiple gpios in gpio-hog
Markus suggested the discussion about the discussion
"Device tree binding documentation for gpio-switch"
and on that, label is used. Also for names, "label" is going to very
So I added new property "label" to support multiple names.
